Take a journey back through the history of the Earth through the University of California Museum of Paleontology’s online exhibit Geologic Time Scale. Jump to a specific time period using the time scale and examine ancient life, climates, and geography, or start in the Cenozoic Era (65.5 million years ago to the present) and work back through time, or start with Hadean time (4.6 to 4 billion years ago) and journey forward to the present day. Additional information about plate tectonics and the geologic time scale’s origins and time divisions is included.
